Key Features
- Genuine OEM Sealing Materials — Manufactured to Genie's original material and compression specifications, delivering the same sealing performance as the factory-installed kit for cylinder 61428GT.
- Cylinder-Specific Fit — Engineered exclusively for the primary lift cylinder 61428GT, so every seal, O-ring, and wiper in the kit corresponds directly to the correct bore and groove dimensions.
- Z-80/60 Compatibility — Confirmed fitment for the Genie Z-80/60 articulating boom lift, a machine operating at significant working heights where component integrity is critical.
- Restore Full Cylinder Function — A worn or failing cylinder seal causes fluid weepage, loss of lift pressure, and inconsistent boom movement. This kit restores proper cylinder operation and holding force.
- Safety-Relevant Component — Cylinder seals directly affect the boom's ability to hold position under load. Using the correct OEM seal kit supports the structural and operational integrity required for safe aerial work at height.
A lift cylinder seal kit contains the internal and external seals, O-rings, back-up rings, and wiper seals that keep fluid contained within the cylinder and prevent contamination from entering. When these seals degrade, the cylinder begins to weep fluid externally or bypass internally, resulting in a gradual loss of holding pressure that causes the boom to drift or fail to extend fully. Replacing the seals at the first sign of weeping restores cylinder integrity and keeps the primary lift function of the boom performing as intended.
